Taiwan's Bull Run Persists While Korea's Market Crashes 44%

Woofun AI reports that the diverging narratives of two neighboring markets have become starkly apparent, contrasting the early end of the World Cup era for a Korean girl with the ongoing rally for a Taiwanese girl. While South Korea's stock market suffered a catastrophic collapse driven by leverage mechanics and extreme concentration, Taiwan's bull run has endured, fueled by a broader base of AI-related equities and more forgiving liquidation protocols. This divergence highlights how structural differences in market composition and regulatory frameworks can lead to vastly different outcomes even when both economies are exposed to similar global technological trends and retail investor frenzies.

Taiwan's historic market surge in 2026 has redefined its global standing, with the market posting gains of nearly 60% in the first half of the year alone. TSMC led the charge with a 55% increase, while MediaTek saw an extraordinary gain of almost 200%. By the end of June, the total market capitalization of Taiwan's stocks exceeded $5.1 trillion, a milestone that propelled it past the markets of France, the UK, Canada, and India within the same year. This rapid ascent secured Taiwan the position of fifth globally in terms of market value, validating the sentiment that this period represents the "best summer" for Taiwanese investors. The breadth of this rally, extending beyond a single entity to include major chip designers and manufacturers, has provided a robust foundation for sustained growth, distinguishing it from more concentrated market structures elsewhere in Asia.

In sharp contrast, South Korea's market collapse in July was severe and rapid, triggering circuit breakers multiple times as the KOSPI plummeted from 9,384.59 points at the end of trading on July 19 to 5,262.77 points on July 29. This drawdown of 43.93% represented a monthly decline of 37.91%, marking the third-worst single-month performance in the country's stock market history, surpassed only by the Asian financial crisis in 1997 and the global financial crisis in 2008. The speed of the reversal was further illustrated by the balance of credit trading financing, which hit a record high of 38.63 trillion won on June 24 but dropped to 28.93 trillion won by July 31. This reduction of nearly 10 trillion won in just one month underscores the fragility of the rally, highlighting the severe financial distress faced by retail investors.

Taiwan's resilience is further evidenced by the deepening investment culture among younger generations, with interest spreading from universities to junior high schools. In June, a TV station filmed a program at Dongwu University's securities study club, where students analyzed reports and backtested strategies under the guidance of seniors like Luo Dexuan, who began investing during the main upward trend last July. Luo noted that student discussions are driven by trading volume, with high-volume days sparking conversations about missed opportunities.

Similarly, Ye Jiayou, another member, started investing in his ninth grade, initially buying stable stocks like 0050 and TSMC before shifting to active positions in Micron and SanDisk due to the strong performance of memory chip stocks. This trend is not isolated; Wanhua Junior High School has established a "Financial Exploration Club," and students at Hsinchu High School frequently discuss stocks in class, reflecting a societal shift where financial literacy and market participation begin at a remarkably young age.

The wealth underlying this investment culture is particularly pronounced in Hsinchu, a region synonymous with Taiwan's semiconductor industry. According to Ministry of Finance statistics for fiscal year 113 released this year, the average comprehensive income per household in Hsinchu City was 1.771 million New Taiwan dollars, ranking first in Taiwan for seven consecutive years. Hsinchu County followed with 1.632 million, surpassing Taipei City's 1.557 million for four years in a row.

Guanxinli in the East District of Hsinchu City reclaimed the title of "richest neighborhood in Taiwan" with an average household income of 4.592 million and a median of 3.434 million, indicating widespread affluence rather than isolated wealth. This prosperity is rooted in the Hsinchu Science Park, home to over 600 high-tech companies, where dividend income per household in Hsinchu City reached 228,000 New Taiwan dollars, second only to Taipei City's 385,000. The high median income suggests that the entire neighborhood benefits from the tech boom, creating a fertile ground for stock market participation.

Woofun AI notes that this familiarity with stocks is deeply embedded in the lives of Hsinchu residents, particularly through the legacy of TSMC's employee dividend policy. Before its reform in 2008, TSMC issued additional shares as rewards based on face value, allowing early engineers to accumulate large amounts of stock at very low costs. One share represented 1,000 underlying shares, and at TSMC's price of 2,395 New Taiwan dollars on August 11, one share was worth 2.395 million New Taiwan dollars.

Thus, holding 'hundreds of shares' translated to a market value of hundreds of millions of New Taiwan dollars, making TSMC not a distant blue-chip stock but a tangible asset in many families' accounts. Children in these households often hear discussions about ex-rights and dividends from a young age, normalizing stock ownership and long-term investment strategies. This intergenerational transfer of financial knowledge and assets has created a unique ecosystem where stock market participation is viewed as a natural extension of family wealth management, rather than a speculative activity.

The retail frenzy has extended beyond tech hubs, permeating everyday life across Taiwan. Taxi drivers check stock prices on their phones while waiting for passengers, with some drivers watching the market until 1:30 p.m. instead of working. A chairman of a listed company noted the difficulty of finding a taxi at 9 a.m. in central Taiwan due to this behavior. The allure of quick profits has led some to abandon traditional careers; a 27-year-old firefighter made about 700,000 New Taiwan dollars trading TSMC stocks in two months before quitting to trade full-time, describing high-dividend stocks as a way of "wasting money" and a 9-to-5 job as "slavery mentality".

Bloomberg interviewed a 26-year-old unemployed man who borrowed money to buy Taiwanese tech stocks worth about $60,000, claiming 'you can make money by buying just any stock.' A job-seeking platform estimated that about 310,000 people in Taiwan were considering or choosing to 'quit their jobs to trade stocks,' with nearly 40% being beginners. This sentiment reflects a broader societal shift where the potential for rapid wealth accumulation in the stock market is seen as a viable alternative to traditional employment.

Structurally, Taiwan's and South Korea's stock markets share significant similarities, including concentration, retail dominance, and leverage. TSMC alone accounts for 43.79% of Taiwan's overall market, while the top ten largest stocks make up 61.01%. In South Korea, Samsung Electronics and SK Hynix dominate the index to a similar extent. Both markets are heavily influenced by retail investors; in March, intraday cancellations accounted for 36.47% of Taiwan's total trading volume, with an average of 192,600 accounts engaging in day-trading, and individual investors accounting for 53.73% of total trading volume.

Leverage is also prevalent in both markets. South Korea's peak credit trading financing balance of 38.63 trillion won corresponded to a market cap of 7,993.4 trillion won, resulting in a borrowing ratio of about 0.48%. In Taiwan, the peak financing balance was 813.48 billion New Taiwan dollars against a total market cap of about 150 trillion New Taiwan dollars, yielding a borrowing ratio of about 0.54%. These comparable scales and ratios suggest that both markets were vulnerable to similar shocks, such as negative developments in the AI industry or the listing of CXMT, the third-largest memory chip company in the world.

The July crash highlighted both shared pain and divergent reactions. On July 17, Taiwan's weighted index dropped by 2,953.71 points, or 6.47%, setting a new record for the biggest single-day drop, with TSMC falling by 180 New Taiwan dollars. On July 28, the index dropped another 2,030 points, hitting a low of 39,384.85 points on July 29, a pullback of about 17% from its intraday high.

However, unlike South Korea, Taiwan's market rallied by 3,186 points, or nearly 8%, on July 31. By August 12, the weighted index had returned to 45,518.07 points, only about 4% away from its intraday high. Starting from the last trading day of 2025 at 28,963.60 points, the annual gain remained over 57%, with the market rebounding above 45,000 points. In contrast, South Korea's market continued to suffer from a significant pullback, illustrating how different structural factors can lead to vastly different recovery trajectories despite similar initial shocks.

Why Taiwan survived while South Korea's summer ended can be attributed to diversification and liquidation mechanics. South Korea's rally was driven primarily by Samsung Electronics and SK Hynix, with retail money concentrated in these two stocks and their associated leverage products. In Taiwan, AI is the main driver, but it involves multiple companies, including TSMC's wafer manufacturing, MediaTek's chip design, ASE Group's advanced packaging, and various substrate, PCB, server, cooling, power supply, and network equipment firms. When CXMT went public, all four of Taiwan's major memory chip companies—Nanya Technology, Universal Storage, Winbond, and Powerchip—had their prices limit down, but TSMC only dropped by 2.98%.

Furthermore, Taiwan's forced liquidation thresholds are more lenient; the maintenance ratio is 130% compared to South Korea's 140%. In Taiwan, brokers give two days after notification to raise funds, whereas in South Korea, stocks are sold much faster.

Additionally, Taiwan sells only as much as needed at the current market price, while South Korea calculates the worst-case scenario, assuming a 15% to 20% drop, and sells shares worth 4.5 million dollars to cover a 1-million-dollar gap, or even 7.2 million dollars for high-risk stocks. This mechanical difference led to four circuit breaker triggers in South Korea in July, exacerbating the crash. While Taiwan's bull market may eventually end, its structural resilience has allowed it to endure the summer far longer than its neighbor. This marks a critical divergence in how Asian markets navigate the intersection of technological hype and retail speculation.
